Dear all,

I am looking for thermal cracking temperature (without catalyst assistance) for hydrocarbon specifically paraffin and aromatic. If you know any website, appreciate your advice.

Thanks in advance.

Hi,

can you elaborate, on the nature of the HC, is it gas or liquied. what is the desity/UOP K if you have them. also, for what this information will by used?

the type and origin of HC liquied or gas will be have a significant infulance on the satability of the substance.

Nelson book might have what you are after, if you could give me more info i will see what i can find

cheers,

sm,

Process fluid is a mixtures of C1 to C10 and potentially with BTEX in it. It can be in vapor and liquid form. Density would be big range as it could be in vapor and liquid form (probably 30kg/m3 -700 kg/m3). We found coking in the WHRU and investigating the reasoning behind.

The fluid you just summarized looks more like a petrochamical syn mix rathar than just crude oil fraction. typically C10 will crack at 650 to 750 Deg F range, lighter fractions will crack at a higher temperature. C1-C2 will crack at a temperature of 1200 deg F or above.

could not check nelson book, this is my best estimates.
